So I was listening to Shapiro the other day. I am now convinced Gibbons was asked to leave (fired), but they let him save face by saying he is not interested in a re-build etc.
Basically, Shapiro said, there was nothing wrong with the Clubhouse culture and team culture so to speak. However, if we want to win the AL East it has to be much better and a different mindset and that is what Montoyo brings. In plain English, Gibby was average, they think that Montoyo can be exceptional.
Gibby was fired, plain and simple.
